Crossing the Line (Sinner and Saint, #1) by Lucy Score

"What I feel for you? It's not healthy. It's an obsession."

From the author of the #1 Amazon bestseller Pretend You're Mine, Lucy Score once again delivers an unforgettable, suspenseful love story with the first novel in the Sinner & Saint duet.

Rule-bound Xavier Saint has seen it all from the battlefield to the behind-the-scenes business of protecting Hollywood's elite. His private security firm is the best in the country, but he's sick of protecting vapid starlets from themselves. Which is exactly what he thinks he's getting into with Waverly Sinner, a second generation screen goddess. But she's not just another celebrity on self-destruct.
